Villagers in Jinmi Village, Xiaoling Town, Zhashui, Shaanxi, plant fungus according to local conditions and drive the sale of local agricultural products through live e-commerce selling. The General Secretary has praised, Zhashui fungus red all over the net!!!!
Last night, 20 million people bought up 24 tons of Quashua fungus!
You can't eat fresh fungus!
Black fungus, also known as black cabbage, is China's valuable medicinal food and gelatinous fungi. According to modern scientific analysis, the dried black fungus is high in protein, vitamins and iron, and its protein contains a variety of amino acids, especially lysine and leucine are the most abundant.
However, fresh fungus contains a chemical name for the "porphyrin" special substances, people eat fresh fungus, sunlight exposure will occur plant solar dermatitis, causing itching of the skin, so that the exposed part of the skin red, itchy and painful, resulting in rashes, blisters, edema.
Drying and dehydration breaks down the porphyrins in large quantities.
Black fungus should be dried or dried in a timely manner after harvest. After harvesting the ear pieces still maintain aerobic respiration, if not timely drying and drying, will release a large number of spores, resulting in black fungus autolysis, rot. Therefore, timely harvesting and drying is to ensure the quality of black fungus products is an important level.
The traditional drying method is to spread the fresh fungus in the sun field and dry it, but this way is in direct contact with the outside world, the environment is complex with many variables, and it is greatly affected by the natural uncertainties. There is also the use of earthen kiln fire baking drying room for baking, but the health environment is poor, drying room drying temperature is not easy to control, moisture can not be discharged, a large number of smoke and exhaust will also be on the fungus caused by the "secondary pollution".
Abandon the natural drying, kiln fire baking and other backward ways, now many black fungus growers around the country to build a simple drying room, supporting the PARKOO high temperature dryer can be realized efficient drying.
Black fungus drying process reference
Wash the fresh black fungus with water and put it into a loading tray;
Preheat the dryer at about 50℃-55℃ and then debug the temperature to cool down, and discharge the black fungus in the loading tray evenly;
Set the temperature of drying at 35-40 ℃, black fungus drying heat, the surface of a large number of water evaporation out, followed by a gradual reduction in temperature to about 26 ℃, for 4 hours;
Starting from 26 ℃, the temperature increases about 3-4 ℃ every hour, control the relative humidity of the air about 10%, maintained for 5-8 hours; the temperature rises slowly to 50 ℃ to maintain a constant temperature;
Constant temperature to maintain a constant temperature of 5 ~ 8 hours after the temperature will rise 55 ℃ -60 ℃ after the overall drying; black fungus drying eighty percent, take out and spread to dry for 2 hours to continue to dry, to be all dried that is the end.
PARKOO-enclosed internal circulation drying system
1、Baiao dryer refers to the principle of inverse Carnot, and has two functions of closed moisture removal and temperature rise at the same time;
2、Intra-circulation closed drying, 10～98%RH adjustable, using high temperature to volatilize the water inside the material, rapid drainage through the internal circulation dehumidification system to reduce the humidity of the drying room;
3、No need for strong exhaust air dehumidification, reduce the loss of heat source in the drying process;
4、Simple operation, high degree of intelligence, the use of temperature and humidity control device, can be 24 hours continuous operation;
5、Environmentally friendly, no pollution, no emissions, in line with the national advocacy of low-carbon policy.
Equipment Installation Schematic
PARKOO high temperature dryer, suitable for indoor temperature higher than 38 ℃ lower than 55 ℃ environment drying and dehumidification, there are ultra-high-temperature dryer, applicable to the temperature of 65 ℃ or less, drying and dehumidification integration, accurate temperature and humidity control, to create a suitable environment for drying black fungus, high efficiency and speed, energy saving and environmental protection.
